3M High Performance Green Masking Tape 401+ is a 6.7 mil crepe paper tape with a natural/synthetic rubber blend adhesive, engineered for demanding masking work where sharp paint lines, solvent resistance, and clean removal are non-negotiable. Also designated 3M 233+, it delivers strong surface adhesion while conforming to curved and irregular profiles without lifting or flagging.

This tape is built for spray painting operations, powder coating preparation, and production-line masking in automotive, aerospace, and general manufacturing environments. Its resistance to paint bleed-through and solvents keeps edges defined through the full coating process, and its conformability makes it reliable on contoured parts, door jambs, and irregular assemblies.

Rated to withstand 250°F for up to 30 minutes, the tape removes cleanly in one piece after heat exposure, minimizing surface rework. Each case contains 16 rolls and ships via parcel carrier.
